Nintendo Switch hits store shelves in just a few months, but Nintendo is staying tight-lipped (at least until January 12th) about its software lineup. In the meantime, various reports have been leaking details ahead of the official reveal, and today we have a new report from Laura Dale of Let's Play Video Games. According to sources at both Nintendo and Ubisoft (who have proven accurate in the past), Nintendo Switch is getting a Mario & Rabbids crossover RPG.

Dale reports that Ubisoft is developing a turn-based RPG under the watchful supervision of Nintendo. The game has the working title "Mario RPG: Invasion of the Rabbids," and Nintendo is aiming to make it a launch title for Nintendo Switch.

The game's plot revolves around the Mario universe being invaded by Ubisoft's Rabbids characters, some friend and some foe, and Bowser (who has a new form based on the design of the Rabbids) will be a recurring boss. Yoshi will be a key member of your party, as will a playable Rabbid, and there will be numerous cameos from other Mario characters. The game features an auto-save feature to ensure that players won't lose their progress if their battery dies while playing on the go, and the Joy-Con controllers are said to vibrate to indicate a Rabbid jumping into and out of them from the TV or handheld screen.

This title is said to be one of the focuses of the upcoming Nintendo Switch presentation in January, and Nintendo intends to have a playable demo ready for the press at that time.
